As a counterpoint to the post earlier today:
My brother signed up for WoW this afternoon. He called in to upgrade from trial to full account, and was very happy with how things went. The woman on the phone was uncharacteristically eager and cheerful and even bantered with him a bit. He sounded as through the experience may even have been uplifting.
He got the same story: It’s much easier to simply run to the store than to upgrade a trial account. (That is, ignoring the trip to the store.) He didn’t mind, and in fact ran out and got the fancy edition that includes Burning Crusade and strategy guides and whatnot.
And now he’s home, and will spend the rest of the evening downloading patches.
